COLTER-CL'ANI P.V

SPECIFICATION forming part of Letters Patent No.` 611,655, dated October 4, 18984.

Application filed April 23 1 8 9 8.

To @ZZ whom, it may concern.-

Be it known that I, HENRY IvENs STONE, a citizen of the United States, residing at Gurdon, in the county of Clark and State of Arkansas, have invented a new and useful Colter-Clamp, of which the following is a specification.

The invention relates to improvements in colter-clamps.

The object of the present invention is to improve the construction of colterclamps and to provide a simple, inexpensive, and efficient device adapted to strengthen a plowbeam where the shank of the colter passes through the same and capable of securely holding a colter at the desired adjustment, so that the same will readily cut through the turf of new ground and through roots and the like. V y

A further object of the invention is to enable the colter of a plow to be readily removed when it is desired to sharpen the same and to permit `the clamp to remain on the beam, so that it will not become lost or separated from the plow. Y

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a colter-clamp constructed in accordance with this invention and shown applied to a plow-beam. Fig. 2 is a vertical sectional view taken longitudinally of the beam. Fig. 3 is a similar view taken transversely of the beam. Fig. 4 is a detail perspective view of one of the members of the clamp.

Like numerals of reference designate corre- .sponding parts in all the figures of the drawings.

l designates a clamp composed of two similar sections 2, adapted to embrace a plowbeam 3 at the slot or opening 4, through which the shank or stem 5 of a colter 6 extends, and the said sections are adapted to clamp the shank of the colter and hold the same at the desired adjustment. Each section 2 is provided at its upper and lower edges with substantially L-shaped flanges 7 serian. 678,597. (No man.)

and 8, extending inward over the upper and lower faces of the plow-beam and engaging the shank of the colter at opposite sides thereof.

The horizontal portions of the iianges 7 and 8 fit the upper and lower faces of the plowbeam, andthe vertical flanges, which form engaging faces, are provided with perforations 9 and l0,`through which pass bolts 1l and l2, located in advance and in rear of the shank of the colter. The bolts, which are adj ustable, are adapted to be arranged in any of the perforations 9 and l0, and they perform two functions, being adapted to cause the iianges to clamp the colter and being designed to be arranged adjacent to the front and rear edges of the same, as clearly shown in Fig. 2 of the accompanying drawings. The bolts, by being arranged' at the edges of the shank of the colter, are adapted to support the same in an inclined position, and the inclination may be varied by arranging the bolts in the and also serve to support the shank of the colter, and they may be readily changed to vary the inclination of said shank. The device is also adapted t'o permit a colter to be readily removed from a plow for the purpose of sharpening it, and the clamp is adapted to remain on the beam while the colter is being sharpened.

What I claim is- In a device of the class described, the combination with a plow-beam having a slot, of a colter extending through the slot, and a clamp composed of clamping sections arranged at opposite sides of the plow-beam, conforming to the configuration of the same, and provided with upper and lower L--shaped flanges fitting against the colter and having perforations, and fastening devices passing through the perforations of the sections and my own I have hereto axed my signature in adapted to cause the same to engage the colthe presence of tWo Witnesses.

ter, said fastening devices being also arranged T at the front and rear edges of the colter to HENRY IVEBS STONE' 5 support the saine at the desired inclination, Witnesses:

substantially as described. F. D. BROWN, In testimony that I claim the foregoing as BENv BUSSELL.
